JOSEPH LEWIS JENSEN, OF RICHFIELD, UTAH.

BEET-BLOCKING MACHINE.

Application filed January 25, 1916.

To all whom t may concern Be it known that I, JOSEPH L. JENSEN, a citizen of the United States, and a resident of Richfield, in the county of Sevier and State of Utah, have invented certain new and useful Improvements in Beet- Blocking Machines, of which the following is a specification. Y

My invention relates to the cultivation of sugar-beets, cotton, and other plants, and the main 'object thereof is to provide a machine adapted to be drawn or otherwise propelled transversely of the substantially parallel rows of plants in Order to block out, thin, or cut away plants not wanted and to leave plants that are wanted.

A further object is to provide such a device which protects the plants which it is desired to retain from injury, but which cuts away vegetation of all kinds between said plants, in all of the parallel rows of plants traversed; and a further object is to provide such a device which may beractuated, in whole or in part, to clear or avoid plants in the event o-f their not being symmetrically arranged, but which it is desired to retain.

My invention is fully described in the following specication, of which the accompanying drawings form a part, in which the separatel parts are designated by the same reference characters in each of the views, and in which y I Figure 1 is a plan view of a presentpreferred form of my invention, adapted to be drawn by horses; Fig. 2 is a section taken on the line 2-2 of Fig. l; Fig. 3 is aV fragmentary, detached, view of a detail of the construction; Fig. 4 is a similar view of another detail; and Fig. 5 is a planview of the manner of using the device. l

My invention may be moved or propelled by pulling or pushing, but, for purposes of description, I have illustrated a horse drawn machine which is adapted to be moved transversely of a series of substantially parallel rows 6, Fig. 5, to cut away all undesired plants of whatever kind or class growing between desired plants 7 ,Y thereby insuring a desired spacing of the desired plants, and a substantially symmetrical arrangement thereof, and it will be obvious that the device may be used in connection with any class of vegetation, in the early stages of the growth thereof.

In the form illustrated I have shown an axle 8 having traction wheels 9, which may be provided with cleats if desired, adjustable .along said axle and held iii adjusted position by means of collars 10 and bolts 11, or in any other manner, and said axle also supports a main frame of yoke form composed of two lupwardly and forwardly directed side members 12 and 13 connected, at their forward ends, with a cylindrical head 14 in which is a rotatable spindle or lswivel 15 carrying a wheel or roller 16 at its lower end, preferably oset, and said swivel is provided with outwardly directed, diametrically arranged, arms 17 whereby the machine may be guided in the manner hereinafter set forth, and I also connect the lower part of the head 14 with the frame members 12 and 13 by means of supplemental frame members 18 carrying a shaft or draw-bar 19.

The main frame members 12 and 13 also support a transverse, slotted, guide 20 for a sway-bar 21 extending forwardly beyond the head 14 and in pivotal connection with a centrally arranged, longitudinal, frame member 22 at 23, said member 22 being supported at its rear end upon the axle 8, and carrying a seat 24 upon a spring plate 25 for the driver, and said sway-bar 21 has the tongue 26 pivoted thereto, at 27, in such manner as to permit the vertical movement thereof on its pivot, the sway-bar also carrying the doiible-tree 28 pivoted thereto at 29 when the device is adapted to be drawn by a team of horses.

Also pivoted on the central frame member 22 is a bar 30 the ends of which are connected with the arms 17 by means of rods 31, said bar 30 having a right pedal 32 and a left pedal 33, one on each side of the pivot 34, and pressure on either one of which rotates the swivel 15 in the head 14 and thus guides the machine, said pedals being inoperative proximity to the drivers seat 24, and I also provide .a marker at the ends` of rods 36 and 37 pivoted in eye-bolts 38 and 39 mounted on the 'frame member 22 and the slotted member 20, respectively, and I also provide a yoke 40 in the sway-bar 21 and the arms of which are adapted to engage the outer sides of the main frame members 12 and 13 in order to lock the sway-bar to the frame when the direction of movement is straight ahead, said yoke, when moved lOO llO
